[Booki-dev] Re : Redis

[Aleksandar Erkalovic]

on our installations and on my test environment i download redis
source and compile it (from 2.0 to 2.3). i needed latest versions of
redis before because of some features. also, i would use default redis
configuration from the source (might be different in debian
distribution, knowing debian people). redis is used only for messages.
when you chat in editor, who has locked what chapter, list of chapters
and etc.... deleting .rdb file will not have any impact on the content
of the book, just some information needed for the editor (if someone
is editing chapter, you delete .rdb file other users will not see that
chapter is being edited by xy user).
